I'm also interested to know this? It's been running around 21-22psi since the motor had 5,000km (first tuned). When the first unit failed MRT said it had nothing to do with the tune - just unlucky. EGT's stay below 600C.
The most recent tune was with the new exhaust and cross country intercooler and the tuner was happy to up the boost to around 23-24psi as the oil, water and EG temps are all fine.
The LPG injection injects after the turbo and before the intercooler - there's not massive gains with the gas maybe 5kW of power and 30Nm of torque with the gas on. But certainly more responsive and boost comes on earlier with the gas on and the fuel consumption improves by an entire 2.0L / 100km.
I always let the motor idle for at least 3 mins before switching her off. I've done a bit of research into the VGT's and I know they are more sensitive to soot contamination and bearing temperatures. I don't fully understand what is killing the turbos so quickly on my car and of course Mitsubishi never tell you anything - I'm very interested what component is actually failing - I'll see if I can get any info out of the dealer when they look over the vehicle tomorrow morning.
